Department: Atmospheric Sciences

Position: Professor

Research Interests: My research and that of my students has been directed at improving our understanding of global climate and its year-to-year and decade-to-decade variations, making use of observational data. We have contributed to the identification and understanding of a number of atmospheric phenomena, including the vertically propagating planetary waves that drive the quasi-biennial oscillation in zonal winds in the equatorial stratosphere, the 4-5-day period easterly waves that modulate daily rainfall over the tropical oceans, and the dominant spatial patterns in month-to-month and year-to-year climate variability, including the one through which the El Nio phenomenon in the tropical Pacific influences climate over North America.
